Environment variables

If it’s keys, then use secrets and configure them in the
package.json:

1"now":{

2"alias":"cool",

3"env":{

4"AWS_ACCESS_KEY_ID":"@aws_access_key_id",

5"AWS_SECRET_ACCESS_KEY":"@aws_secret_access_key",

6"MONGODB_URI":"@mongodb_uri",

7"S3_BUCKET_NAME":"@s3_bucket_name",

8"SECRET":"@secret"

9}

10},

If you have a lot of configuration variables and you dont want to make
a mess in the package.json:

1now -E

That will pull your .env file and use that in place of adding
individual vars via now -e var. I have always used dotenv and I
understand that now uses dotenv for this and using without is
untested by me?
